We added the train you requested to our To-Do list for v0.8.1, thanks for your request and especially for your extensive explanation. It's great to have someone tell us a bit about the trains they request, it appears you have pretty specific reasons to ask for that very train. Or is it just a favorite of yours? ^.^
Once again, thank you for your amazing feedback, you brightened our day!
Hi, thank you for considering my suggestion for your mod, it is very kind of you.
E-269 and Serie 10000 of Terrasur Temuco are a very favorite train of mine. I'm Chilean, so the train is from where I live. Is one of the last long distance trains EFE has, composed by locomotive and cars, as they are turning into railcars for passenger traffic. Since the mod has a Japanese inspiration, I think you would like to search for some info and know about the AEZ and AEL series, built by Nissho Iwai, Kawasaki Heavy Industries and other Japanese companies about '70s for EFE.
